Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a brain wave induction device using a low frequency magnetic field.

(Prior art) According to conventional research on cerebral physiology, brain potentials, or brain waves, are generated in the human cerebrum in conjunction with the activity of brain cells, and that different brain waves are generated depending on the state of activity of the cerebrum. Among them, beta waves of 13 to 30 Hz occur during wakefulness, alpha waves of 8 to 12 Hz occur during relaxation during meditation or hypnosis, and theta waves of 4 to 7 Hz characteristically occur during the sleep onset period. There is.

(Problems to be Solved by the Invention) From the above, brain cells are electrical conductors and can be considered as electrical circuits in which electricity is constantly generated and flowing.

(Technical problem of the invention) The present invention solves stress, irritation, anxiety, phobia,
Provides a low-frequency magnetic field generating device that can be used by people suffering from insomnia or during meditation or hypnosis to effectively stabilize the mind, quickly induce a meditative or hypnotic state, and does not make contact with the human body. The purpose is to

(Means for Solving the Problems) The present invention is an apparatus that electromagnetically induces brain waves associated with an awake state, a relaxed meditative state, or a hypnotic state by applying a low-frequency magnetic field to the brain of a subject. It consists of a transistor TR or integrated circuit IC, a resistor, a sine wave generation circuit for the CR oscillator using a capacitor, a power amplifier to obtain a strong sine wave current, a coil for generating a low frequency magnetic field, and metal fittings to fix it. It consists of.

(Action of invention) The operation of the present invention will be explained.

Taking advantage of the fact that brain cells are electrical conductors,
A sinusoidal current is passed through a coil placed close to the cerebrum to generate lines of magnetic force due to a low-frequency magnetic field, as if changes in the lines of magnetic force interlinking with an electric circuit cause an electromotive force to occur in that circuit, causing a current to flow. When applied to brain cells, an electromotive force equal to the frequency of the low-frequency magnetic field is generated within the brain cells due to electromagnetic induction, which acts as if brain waves were generated, stimulating the activity of the brain cells, and It is an active device that induces consciousness into a state of mental unity (brain waves are alpha waves or theta waves) or a state of wakefulness (brain waves are beta waves), and has no effect on the human body. Since it is a contact, it is electrically safe.

(Example) Embodiments of the present invention will be described based on the drawings.

In FIG. 1, this device is a configuration diagram including a CR oscillator 1, a DC voltage amplifier 15, an output regulator 16, a DC power amplifier 17, a lead wire 18, and an air-core coil 19.

CR oscillator 1 is a Wien Bridge oscillation circuit consisting of FET 2, transistor 3, clamp diodes 4, 5, resistors 10, 11, and capacitors 7 to 9, 12 to 14, and generates a sine wave with a time constant by the resistors and capacitors. I can do it.
The circuit of FET 2, transistor 3, and additional resistance of CR oscillator 1 is a linear integrated circuit with FET input.
Can be replaced with IC.

The oscillation frequency for inducing brain waves is performed by switching the linked changeover switch 6, and can be set by the values of the capacitors 7 to 9 and 12 to 14 connected to this, and in this case, the values of the resistors 10 and 11. teeth
390KΩ, the capacitance value of the capacitor is 7 for β waves,
0.033μF for 12, 0.076μ for 8 and 13 for alpha waves
For F and θ waves, 0.15 μF is used for 9 and 14.

To stabilize the amplitude of this circuit, AGC is used that shifts the average gate voltage of FET 2 using clamp diodes 4 and 5, so there is no time constant in the amplitude stabilizing circuit, so it is stable even at low frequencies. Stabilizing the power supply voltage also stabilizes the frequency.

This output waveform becomes a sine wave, and this output is passed through a DC voltage amplifier 15 and sent from an output regulator 16 to a DC power amplifier 17 (output 10W to 20W), where a strong low frequency sine wave current is generated.
This current passes through the lead wire 18 and the air core coil 19.
(300 to 600 turns), which generates a low frequency magnetic field (500 to 1500 Gauss).

When using this device as shown in FIG. 2, first, the subject is placed on his/her back using a pillow 25, and the air-core coil 19 with the coil fixing fitting 24 attached to the head is placed in advance.
When attempting to induce a meditative or hypnotic state from an awake state by approaching a suitable position, the oscillation frequency selector switch 6 is set to the alpha wave position or the theta wave position. The magnetic field lines of alpha waves or theta waves are emitted from the air-core coil 19, which acts on brain cells, stimulates brain activity, relaxes the brain and body, and unifies the mind, resulting in meditation or hypnosis. can be conducive to the situation.

When attempting to induce a state of wakefulness from a meditation or hypnotic state, the changeover switch 6 is set to the β wave position. Beta-wave magnetic lines of force are emitted from the air-core coil 19, which can similarly stimulate activity in the brain and promote a state of wakefulness in the brain and body.

Note that the air-core coil 19 can be easily removed from the coil fixing fitting 24, and the air-core coil 19 can be used alone.

(Effects of the Invention) The present invention allows a current of a sine wave signal (such as α wave), which is a basic component of brain waves, to flow through a loop coil as an electrical signal with a frequency similar to that of brain waves, and causes the coil to generate a sine wave signal. Generates fluctuating lines of magnetic force due to the magnetic field. Then, just as a change in the lines of magnetic force interlinking with an electric circuit (conductor) near the coil causes an electromotive force (eddy current) to flow in that circuit, when it acts on the brain, it causes brain cells and Inside neurons, there is an electromagnetic induced electromotive force (such as alpha waves) that is equal to the frequency of the magnetic field lines of a sinusoidal signal similar to brain waves.
happens. This is exactly the same state as when brain waves are generated, and changes in cell potential activity stimulate the activity of neurons (neurons) and synapses, causing chemical reactions and causing the aforementioned neurotransmitters (peptides). It is possible to induce consciousness and mental state to the desired state (meditation or hypnosis) by increasing or decreasing the amount of metabolites, etc. (e.g., uridine, uridine, etc.), and it is more effective than methods that involve attaching electrodes to the scalp. Since there is no contact, handling is easy. Since the constituent substances of the human body are diamagnetic and paramagnetic,
There is no shielding effect on magnetic lines of force and they pass through. Therefore, the magnetic lines of force uniformly pass through the entire head, and the electromagnetic induced electromotive force does not decrease even deep inside the brain, resulting in a good effect.
